Objective To explore the correlation of RELL1 expression with clinical pathological features and prognosis of patients with colon cancer.Methods Immunohistochemical experiments of the RELL1 protein were performed on tissue chips from 80 colon cancer tissues and 80 adjacent tissues.The relationship between different expression levels of RELL1 protein and clinical pathological parameters was compared.Univariate and multivariate Cox risk proportional regression analyses were conducted on factors affecting the survival of patients with colon cancer.Kaplan-Meier survival curve analysis was conducted on the survival rates of patients with colon cancer and different levels of RELL1 expression.Log rank test was performed to evaluate differences in survival rates.Results The expression of RELL1 in colon cancer tissues was lower than that in adjacent tissues(P<0.05).The expression of RELL1 in cancer tissues is correlated with TNM stage and N stage(P<0.05).The 3-year overall survival(OS)rate of colon cancer patients with high RELL1 expression was higher than that of patients with low RELL1 expression(P<0.05).Multivariate Cox regression analysis showed that low RELL1 expression,advanced age,and high TNM stage were risk factors for poor prognosis in patients with colon cancer(P<0.05).Conclusion The expression of RELL1 is downregulated in colon cancer tissue,and the low RELL1 expression,advanced age,and high TNM stage can lead to adverse outcomes in patients.

Objective The aim of this study is to explore the changes of expression of integrin αvβ3 in bovine u-terine epithelial cells in vitro induced by estrogen or/and progesterone alone or in combination,and to provide a new refer-ence marker for determining bovine uterine receptivity state. Methods RT-PCR was used to analyze the transcriptional changes of αvβ3 expression in bovine endometrium treated by different concentrations of estrogen,progesterone alone or in combination. Results The expression of integrin αvβ3 reached the highest level when the culture medium was added with progesterone at the concentration of 10 -7mg/mL,and the expression of αv and β3 in the 10 -7mg/mL concentration group was significantly higher than that of the control one(P<0.05). Moreover,the expression of αv was highest in the 10 -10 mg/mL E2group,but the expression of β3 was the lowest in that one. In addition,adding with both estrogen and progester-one,the transcriptional level of integrin αvβ3 was significantly higher than that in the control one. The transcriptional level of αv in the treatment group was significantly higher than that in the control group(P<0.05),but the transcriptional level of β3 in this group was not(P>0.05). Conclusions It can be concluded that integrin αvβ3 can be used as a new poten-tial reference marker gene for detecting the bovine uterine receptive status.

The shortage of donor lung remains one of the major problem for lung transplantation?With the development of modern lung preservation and repair technique, increasing marginal lung donors have been re?assessed and finally utilized for transplantation? The ex vivo lung perfusion technique ( EVLP ) was designed and has been developed for evaluation and repair of the lung? Nowadays, the indication of EVLP and the standard of qualified donor lung have reached a consensus according to the foreign publications? The EVLP system could be classified into three categories: the Toronto technique, the Lund technique and Hannover?Madrid technique? The major differences between the Toronto technique and the other two technique are the open left atrium status, the use of Steen solution mixed with erythrocyte and the perfusion at flows correspondent to 100% of the donor predicted cardiac output? With the accumulating experience, researchers have tried to imply some drugs in the circulation, modify the ventilation gas and delivery of adenoviral vector gene in order to improve the lung quality? But these are still in the research phase? Recently, the portable EVLP device has been developed and the lung preservation, assessment and repair could be conducted during transportation? So it could prolong the preservation time and expand the transportation distance of donor lung.

Objective To study the indication,feasibility and short-term efficacy of combined thoracoscopic and laparoscopic radical esophagectomy for the treatment of esophageal cancer.Methods Retrospective medical records analysis was conducted for 139 esophageal cancer patients who underwent combined thoracoscopic and laparoscopic esophagectomy in our department from December 2009 to August 2011.The tumors were located in upper esophagus in 16 cases,middle esophagus in 107 cases,and lower esophagus in 16 cases.The surgery started with the thoracoscopic mobilization of thoracic esophagus and lymph nodes dissection,which were followed by the laparoscopic stomach mobilization and gastroesophageal anastomosis in left neck.Postoperative pathological staging identified stage Ⅰ esophageal cancer in 25 cases ( stage Ⅰ a:13 cases,stage Ⅰ b:12 cases),stage Ⅱ esophageal cancer in 71 cases,stage Ⅲ esophageal cancer in 31 cases ( stage Ⅲ a:16 cases,stage Ⅲ b:15 cases) and stage Ⅳ esophageal cancer in 12 cases.Results Except for open conversions in 4 cases (2.9％),all surgical operations were completed smoothly.Postoperative anastomotic leak was found in 6 cases(4.3％ ),chylothorax in 1 case(0.7％ ),arrhythmia in 4 cases(2.9％ ),and dumping syndrome in 1 case( 0.7％ ).All of these complicated cases fully recovered after conservative treatments.Postoperative lung infection was found 11 cases (7.9％),3 of whom required tracheotomy and assisted ventilation and 1 case died as a result of the infection (mortality rate:0.7％ ).Ten cases(7.2％ ) presented with hoarseness postoperatively.Out of the 139 cases,130 cases were successfully followed up with durations ranged from 1 to 20 months,during of time the esophageal cancer spread to liver in 2 cases,celiac lymph nodes in 4 cases,lung in 2 cases,and bone in 1 case.Ten cases died,and all remaining cases remained alive during the follow up.The one-year survival rate was 88.9％ for these cases.Conclusion Combined thoracoscopic and laparoscopic radical esophagectomy is a technically safe and feasible treatment for esophageal cancer.The short-term efficacy results are satisfactory.This technique is indicated not only for early and middle stage esophageal cancer,but also for some of the advanced esophageal cancer cases.

Objective On basis of physical dose optimization, LQ model was used to investigate the difference between the curves of biological effective dose and physical isodose. The influence of applying the biological dose concept on three dimensional conformal radiotherapy of prostate carcinoma was discussed. Methods Four treatment plannings were designed for physical dose optimization: three fields, four-box fields, five fields and six fields. Target dose uniformity and protection of the critical tissue -rectum were used as the principal standard for designing the treatment planning. Biological effective dose (BED) was calculated by LQ model. The difference between the BED curve drawn in the central layer and the physical isodose curve was studied. The difference between the adjusted physical dose (APD) and the physical dose was also studied. Results Five field planning was the best in target dose uniformity and protection of the critical tissue -rectum. The physical dose was uniform in the target, but the biological effective doses revealed great discrepancy in the biological model. Adjusted physical dose distribution also displayed larger discrepancy than the physical dose unadjusted. Conclusions Intensified Modulated Radiotherapy (IMRT) technique with inversion planning using biological dose concept may be much more advantageous to reach a high tumor control probability and low normal tissue complication probability.

Objective To evaluate the outcome , side effects and prognosis of prostate carcinoma treated with external radiotherapy. Methods From 1990 to 1999, a total of 45 prostate carcinoma patients were treated. Four cases were lost during follow up. Forty one patients underwent orchiectomy before radiation therapy , 29 received orchiectomy combined with hormone treatment. All patients received conventional radiation therapy with a median dose of 68.3 ?Gy (50.4 75.9?Gy), 1.8 2.0?Gy per fraction, five fractions weekly. Results The median follow up duration was 28 months (1 111 months). The overall 5 year survival was 76.4% and the 5 year disease specific survival was 76.5%. In terms of acute GI side effects, the frequencies of Grade Ⅰ, Ⅱ or Ⅲ reactions were 53.5%, 7.0% and 9.3% while Grade Ⅰ or Ⅱ , acute GU side effects were 41.9% and 4.7%, respectively. For the long term deleterious effects,Grade Ⅰ or Ⅱ in GI late complications were 16.7% and 7.1% and the GU late morbidities of Grade Ⅰ,Ⅱ or Ⅲ were 23.8%, 4.8% and 2.4%, respectively. Regional lymph node metastasis was closely correlated with both overall survival (P= 0.002 ) and disease specific survival (P= 0.002 ). Multivariate analysis revealed, only regional lymph node metastasis was of prognostic value to predict the overall survival and disease specific survival. Conclusion The outcome of radiation therapy for patients with T 2 T 4 prostate carcinoma is satisfactory with the side effects tolerable to most patients.
